Genetic Variation of Different Crosses of Linseed (Linum usitatissimum L.) Genotypes for Some Agro-morphological Traits
Yared Semahegn Belete and Misteru Tesfaye Wolde Yohannes

Abstract:
Linseed is among the most important oilseeds in the highlands of Ethiopia, for which yield enhancement is among the breeding objectives. Variability of the genotypes is paramount importance for selection in any breeding programs. This study was carried out in 2012/13 cropping season to determine the genetic variability of 25 linseed genotypes derived from various crosses including checks. The experiment was laid out using a 5x5 simple lattice design with two replications. The analysis of variance revealed that the genotypes showed significant differences for most of the traits measured. High phenotypic and genotypic coefficients of variation were recorded for number of seeds/plant and number of capsules/plant. High heritability along with high genetic advance was observed for number of seeds/plant which indicates selection of this trait at early generation would be effective. Number of primary branches, number of secondary branches, number of capsules and number of seeds/plant showed highly significant positive correlation with seed yield/plant. But, 1000 seed weight had highly significant negative correlation. In cluster analysis it has been shown that the genotypes were placed into six groups, for which further effective selection/hybridization could be done.
